si'ovE ATTACHMENT;

Application filed June 20, 1903. Serial No. 162,434.

Too/M whom it may concern.-

Be it known that I, JAFEW S. VAN BUREN, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and use ful Improvements in Stove Attachments; and

I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to I0 which it apper'ta ins to make and use the same.

My invention relates to improvements in gas burning appliances for stoves, furnaces, etc.

It has for its object to provide an attachment of this cl.=a=-- at 1" which will promote efficiency in completely consuming the gas evolved and which cannot become choked with ashes,

In the accompanying drawings, illustrating the preferred embodiment of'my' invention, Figure 1 is a front view or outline of a stove,

0 partly in central section, provided with my improved attachment; and Fig.2 is a partial sectional View taken through the'blast-belt and showing the supply-door, the drum driven on the flange of the upper section of the blast- 5 belt, and the deflector.

Referring more particularly to the drawings, 1 is the fire-pot, it is the drum, and 3 is the blast-belt, which is located without and preferably completely encompasses the stove be 3 tween the fire-pot and the drum. Said blast belt is composed of two sections or rings, 3 and 3*, made of suitable metal, the lower one resting on a step or projection 4 on the outer Said lower section is i surface of the fire-pot.

itself preferably stepped in order to give the.

belt suficient capacity. The outer edge of the upper section 3 rests upon theouter portion of the lower section 3*, from thence curves upwardly and inwardly and is provided with t a shoulder 5, projecting upwardly for the reception of the drum. Said upper section curves do wnwardly and inwardly from said shoulder leaving a preferably gradually-widening passage 6 between itself and the fire-pot as it apl5 proaches the level of the fire The shoulder 5 Qs preferably sloped or beveledon its outer surface in order that the drum may be driven thereon, thereby stretching the portion of said (No model.)

drum coming in contact therewith and makmg a tight oint. 7 Any expansion of the firepot will serve to make the joint tighter.

There is no'connection'between the'blast-belt and the direct draft; Air is fed into the belt.

through an adjustable door or damper 7 in the front of the stove just below the'feed-door.

A deflector 8, which may have its lower edge out out to form an ornamental design, as shown, arranged on the outer edge of the draft-belt, adds to the appearance of the stove and greatly increases the heat on the floor. ters the blast-loelt through the door or damper above referred to, is heated to a very high he air en-t temperature, and passesinto the fire directly over the surface where thegases are forming. This admixture makes the gases combustible. Perfect combustion is thus secured, and the heat evolved by this secondary combustion of gases is about twice-that evulred the first combustion in whichthegases are formed.

Special advantages of my deviceare that the blast-belt. cannot become-filled up with ashes, there is no tube or ring to burn out, the blast-belt is sufficiently largeand heavy to heat the requisite volume of air and to heat it to the desired temperature, and the blast is delivered at the proper point namely, directly over the surface of the fire-"evenly all around the fire-po.t.

. It is to be understood that I do not limit myself to the details of construction herein claim as new,.and desire to secure iii-Letters Patent, is?- Q. i

1. in a device f thecharacter described, the cornbination'iwith' aIfire-tpotand drum of a fuel-burning apparatiis of an 'extcriorblast belt having-an inner overhanging flange provided with an enlargement, around its inner edge.

drum of a fuel-burning apparatus of a blastbelt carrying an external and "imperfo'rate downwardly curving deflector adapted to described, asthey may be changed at-will and he spiritof my invention remain intact andb6 Protected. ff I Havin g thus described my invention, what I 2. The combination with the fire-pot and throw the heat downward and forming a pocket in which the heated air assists in heating the air-chamber. V

3. In a device of the character described, the combination with the fire-pot and drum of a fuehburning apparatus, of an exterior blastbelt comprising a lower section, resting upon a flange on the fire-pot, and an upper section wholly supported by said lower section, said upper section forming an arch over the upper edge of the lire-pot and extending downwardly within the same forming a circumferential passage for feeding the air upon the fire.

4:. In a device of the character described, the combination with the fire-pot and drum'of a fuel-burning apparatus, of an exterior blastbeltcomprising a lower section, resting upon a flange on the fire pot, and an upper section wholly supported by said lower section, said upper section forr ning an arch over the upper edge of the firepot and extending downwardly within the same forming a circumferential graduated passage for feeding the air upon the 5. In a device of the character described, the combination with the fire-pot and drum of a fuel-burning apparatus, of an exterior blasta flange on the fire-pot, and an upper section wholly supported by the lower section and forming an arch over the upper edge of the fire' pot, said upper section having a flange to belt comprising a lower section, resting upon a flange on thefire-potyand an upper section wholly supported by the lower section and forming an arch over the upper edge of the fire-pot, said upper section having a tapering flange to receive the driven-on drum and extending downwardly Within the fire-pot forming a circumferential passage for feeding air upon the fire.

In testimony whereof I affix my signature in presence of two witnesses,
